ABSTRACT
This article explores the purpose, parameters and structure of the existing information management system in the
organization of freight traffic on the railways of Uzbekistan. This system is called the Automated System for the
Operational Management of Transportation (ASOMT), which for many years has been the main source of information
for making managerial decisions.

INTRODUCTION
It is advisable to study the information-control system
of freight transportation on the basis of the General
Systems Theory. According to the rules of the General
Systems Theory, we can analyze the system in the
following stages:

- the purpose of the information management system
freight traffic;
- elements that make up the information management
system;
- the structure of the information and control system
of freight traffic;
- functional structure of the information management
system;
- interaction with the environment;
- the result of activity.
The information and control system is cybernetic in
nature, since many interconnected objects - elements
of the system, are able to perceive, remember and
process information, as well as exchange information.
The purpose of the information management system
freight transportation is a reflection of the current
state of the operational work of the landfill for making
managerial decisions in the organization of
transportation.
On the railways of the Republic of Uzbekistan as an
information
management
system
freight
transportation is considered to be the Automated
System for the Operational Management of
Transportation (ASOMT).
For a detailed study of the system, we denote the
elements of the system that will significantly affect the
achievement of the goal. An element of the system is
an indivisible part of the system, from the point of view
of the aspect of consideration, the solution of a specific
problem, the goal set.
Elements of the information management system of
the transportation process are divided into two types:
dynamic and static. Dynamic elements change their
characteristics over time and online. Elements of a
statistical type do not change their characteristics in
the online mode.
The
dynamic
elements
of
the
information
management system of the transportation process
include (Fig. 1.1.). :
1.
Train.
2.
Railway carriage.
3.
Locomotive.
4.
Locomotive brigade.
5.
Container.
6.
Sending.
7.
Loading.
8.
Unloading
Static elements include:
1.
Districts.
2.
Line businesses.
When designating the elements of the system, we use
abstraction, since during abstraction, insignificant
details are omitted and attention is concentrated on
the main common properties of a set of elements.
Three types of abstraction are used: classification,
generalization and aggregation.
Classification is the assignment of a set of objects to a
specific element. In our case, covered wagons, gondola
wagons, platforms, etc., are classified as freight
wagons, since they have a common characteristic. As a
result, we get the basic element.

A generalization is a grouping of elements into one
generalized element. Generalization reveals the
similarity of types. All objects related to basic elements
are also generalized elements. Freight wagons have a
common characteristic as non-traction rolling stock,
and are listed under the generic element as Wagon.
Aggregation is the addition of one element to
another in order to obtain one complex element. For
example, a train element can be considered as an
aggregate ( complex element) of a wagon, a
locomotive and a locomotive crew (Fig. 1.1.).

The structure of information systems is formed on the
basis of database models, which is the source of targeted
solutions. The model of the transportation process is
developed taking into account the main required output
solutions of the system. Based on the model, information
can be provided to management personnel on specific
requests. Since the model of the transportation process
is the basis of an automated control system, proper
structuring increases the level of system dynamism. The
information database of ASOMT consists of the following
models of the transportation process (MTP):
1.
Train model of the road.
2.
Locomotive road model.

The main object of control is the wagon. The priority of
information support concerning wagons is the highest.
As an element, wagons are taken into account in a full-
scale way. Most of the operations performed with
wagons are recorded by information points. As a
normative-regulating array of information, an
automated data bank of the freight car fleet (ABD PV)
serves. The automated data bank of the freight car
fleet is a collection of information bases containing
information about the owners, lessees of the cars, the
technical characteristics of the rolling stock,
information about the scheduled and ongoing repairs
of the cars, the range of goods allowed for
transportation, about the permitted areas for the cars
to run.
WRM makes it possible to reflect the following data:
1.
Information on the availability of wagons by
station, sections, international connecting points and
by type.
2.
Information about the location of wagons by
type, by cargo in the wagon, by destination station and
by accessory.
3.
Information about the deployment of special
rolling stock and empty wagons.
4.
Information about statistical data on the
operation of wagons.
Locomotive road model (LRM)
The locomotive road model serves to provide the
following information about locomotives:
1.
locomotive deployment.
2.
Average daily performance of a locomotive in
freight traffic in ton-kilometers.
3.
Locomotive mileage from all types of repairs.
4.
Average daily mileage in freight traffic by type
of traction.
Thus, depending on the state of the locomotives, the
provision of trains with locomotives is controlled. The
information in the model is updated based on
messages sent from the information points.
List of reports from sources about the operation of
locomotives:
1.
Message about the departure of the train - 200;
2.
Message about the arrival of the train - 201;
3.
road exchange message about the operation
with the train, about the locomotives and crews
following with it - 220;
4.
Message about changing the state of the
locomotive - 230;
5.
Message about the unification and separation
of the locomotive section - 231;
6.
Notification of a change in the controlled fleet
of locomotives - 233.
Container Road Model (CRM)
The container model of the road provides the following
information
for
the
organization
of
cargo
transportation:
1.
The current state of the container;
2.
Dislocation of the container;
3.
Search for a container by wagons;
4.
Working with a container

The main message for entering information about
container shipments is a message prepared on the
basis of shipping documents: message 410 about the
acceptance of cargo for transportation (about
sending). In addition, information about containers is
entered on the basis of the train transfer list in the form
of messages p. 421 and 422. The crediting of a container
shipment is issued by message 402. The exchange of
information about containers between roads is carried
out using messages 4770 (0) and 410. To reflect in the
CMD information about the movement of a container
(car with a container) along the road, train messages
02, 09, 200-205 and others.
Brigade road model (BRM)
Operational control of the deployment and work of
locomotive freight traffic crews (OKDB). The object of
control in solving the complex of tasks of the OKDB is
the locomotive brigades of freight traffic in the areas
of their work within the road.
At the road level, the following main tasks are to be
solved:
•
accounting for the presence of locomotive
brigades of freight traffic in the areas of their work, as
well as points of registration and turnover;
•
operational control of the mode of work and
rest of locomotive crews;
•
operational control over the implementation
of the nominal work schedule of locomotive crews;
•
accounting of hours worked per month by
machinists and their assistants;
•
accounting for the presence of a contingent of
locomotive crews;
•
operational analysis of the use of working time
of locomotive crews and rest time at turnover and
home points;
•
formation of a list of indicators transmitted to
the Main Computing Center of the MPS for solving
tasks of the MPS level with the aggregation of
calculation results required for the MPS.
The following information should be sent to the VC of
the road:
•
from allocated stations - the personnel number
of the driver, the time the brigade came to work, the
time the brigade handed over the locomotive;
•
from the depot - the personnel number of the
driver, the time the brigade appeared at work, the time
the locomotive was handed over by the brigade, the
time of arrival and departure of the brigade by the
passenger, data on the cancellation of the brigade's
attendance; reports on granting the brigade a day off,
on the time of illness of the drivers or assistants,
diverting them to other types of work, data on
secondment or granting leave to the brigade, on hiring
and dismissal from work of locomotive brigades;
•
from the road department - data on the
extension of the established duration of continuous
work of the brigades by order of the leadership of the
road department, indicating the reasons.
The basis for solving the set of tasks of the road-level
OKDB is a dynamic brigade road model (BDM), which
includes data arrays about changes in the location and
state of the teams, as well as the actual development
of working hours for each of them.
The BMD keeps records of locomotive crews -
separately for drivers and their assistants.
